It is usually made of reacting with sodium silicate an sulfuric acid, aging as well as acid bubble. It won't react with any material except alkli and hydrofluoric acid. Non-indicating silica gel is both cheap and effective, available loose in bulk packs or packed in sachets.

Activated alumina desiccant This product is a white spherical porous particles, particle size uniformity, smooth surface, high mechanical strength, strong moisture absorption, water absorption expansion does not crack after not intact, non-toxic, odorless, insoluble in water and ethanol. Under certain operating conditions and regeneration conditions, this product can control the dew point to -70&deg;C, and can be regenerated, lowest regeneration temperature to 150&deg;C. the product is widely used in petrochemical industry in gas phase drying and liquid phase drying, textile industry, air separation oxygen industry, automation instrument air dry and pressure swing adsorption (PSA) gas separation device, because the single molecule layer adsorption net heat high, so it is suitable for no heat regeneration device.

It has open porous structure, strong adsorption and adsorption of various substances. Dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, and then become hydrosilicate gel and solid state. Our portfolio ranges from chemical used in industry, agriculture, food to oil and water treatment fields.

2.Turn into gel after absorbing moisture, water trapped into desiccant bag without leaking out. Our main products are silica gel desiccant, active mineral desiccant, calcium chloride and so on. 1) If you have any puzzle or confusion, you can contact with our customer service on Trade Manager.
